SEMISUBMERGED SUBMARINE GUNBoAT AND TOR-PEDO-iaOA-TJ Application file lMay 25, 1909. Serial No. 498,320.

To all whom it may concern:

Be it known that we, HARRY Hnnrznnno, a. resident of the city of NewYork, borough of Brooklyn, county of Kings, and State of New York, AnnorA. Low, a resident of Horseshoe, St. Lawrence county, State of New York,and MAURICE J. or-IL, a resident of the city, county, and State of NewYork, citizens of the United States, have invented certain new anduseful Improvements in Semisubmerged. Submarine Gunboats andTorpedo-Boats, of which the following is a specification.

This invention relates to submarine vessels, and more particularly tothose which are designed to be submerged with the ex ception of aconning tower, though the features of construction and arrangements ofparts may he applied as well to those sub marines that are designed tobe totally sub merged.

Among the objects of the invention are to improve the hull construction,to provide novel and advantageous propelling mech anism, to providenovel quick-acting mechanism for righting the vessel as to pitching, toguard against the entry of water into the body of the vessel through theventilating apparatus, to separate the interior of the 'conningtowerfrom the remainder of the interior of the vessel, and to provide meansfor admitting water to and removing the same from the chamber so formed,for the purpose of quick submerge-nee.

Other obj ects and features ofconstruction will become apparent as thespecification proceeds.

In the accompanying drawings, Figure 1 is a vertical longitudinalsection through a submarine vessel embodying certain features of theinvention, Fig. 2 is a horizontal section through the same,Figs. 3, 4i,5- and 6 are vertical transverse sections through the hullandconningtower on the corresponding section lines of Fig. 1, Fig. 7 is adiagrammatic view of the propelling mechanism, Fig. 8 is a. verticallongitudinal section through a submarine vessel, showing the meansforseparating the interior of the. conning tower from the remainder of theinterior of the vessel, and the means for admitting water to andremoving the same from the'chamber so formed, for the purpose of quicksuhmerg Specification of Letters Patent.

" hem the intenior the remainder of the' i'nte rior d iji For thispurpose we prnvide attibueketihiw adapted to be secured in place so asto extend downward from the base of the eonmng tower into the body ofthe vessel. This,

bucket may be secured at its rim to inner sides of the com'ling towernear the base thereof by any. suitable devices indicated at l 1, and mayhave an aperture through its bottom provided with an upward extend ingtubular flange 12 for fitting around the cylinder (3 or the plm'iger 5.When the bucket is secured as shown in Fig. 8 it forms a chan'iberwithinthe conning tower and partly within the body of the vessel, whichis completely walled off from the remainder of the interior of the hull.Thus, shells or vother 'nrojcctiles entering the tower will be preventedfrom reaching the vital parts of the vessel. Strong water-tight doors.or manholes 13 are provided in the sides of the bucket 10, one openinginward, the other outward. vidcd' 111 the cover 4 of the connmg tower,and 111 the body of the tower. -VV1thin the vbucket may be providedsupports 15 upon which. the occupant or occupants may stand or sit, foroperating the. guns and for maintaining an outlook. through the window16. The chamber formed by the connin tower and the bucket 10 may beutilized fbr submerging the vessel. To this end suitable piping 17extends between an opening in the deck of the vessel and the interior ofthe bucket. This piping is provided with two branches 1S and 19. Infilling the conning tower chamber the water flows through branch 18. Inemptying the chamber this branch is closed and a pump 20 in branch 19draws the water out o the chamber. Suitable-cocks 21 are provided in.the piping.

It will be understood, of course, that the interior of the chamberformed bv the conning tower. and the bucket 10 will be watertight withrespect to the remainder of the interior of the vessel. In thisconnection attention is'called to the provision of packing 22 betweenthe rim of the bucket 10 and i flange 23 on the inside of the conningtower to which the bucket is secured by the devices 11. If desired, thedevices 11 may be released and the bucket disconnected from the piping17, when the bucket 10 may be lowered into the hull of the vessel,permitting of free access to the interior of the conning tower.

An important feature of the invention relates to dualpropelling-mechanism.

The numeral 24 designates twin propellers,

and their shafts. These propellers may be dr1ven,'either by an engine,preferably a gas engine 26, or by a dynamo 27 and storage batteries 28,the latter being conveniently arranged along the sides of the vessel. For driving the propellers directly by the engine 26 the arrangementsare-as follows: 29 are gears on the shafts 25.,

Similar manholes 14. may be prooperation.

weight may'fbe quickly shifted longitudiadapted to be coupled anduncoupled with reference to these shafts by slidable clutch members 35,each clutch member being operable independently, as by a lever 30. 31 isa central gear on the shaft of the engine, being adapted to be coupledand uncoupled with respect to this shaft by a movable clutch member andoperating lever 32. If both of the gears 29 are coupled to their shaftsand the gear 31 to its shaft, both propellers are driven. By shiftingeither clutch member 35 the corresponding propeller is stopped. Byshifting the clutch member 32 both propellers are stopped. Forpropelling the boat electrically the gear 31 is-uncoupled from theengine shaft. The circuit of the dynamo is now closed, as by aswitch 38(see Fig. 7 This circuit supplies two high speed motors 34, whosearmatures are connected with the propeller shafts 25, preferably bybeing mounted thereon. F or greater speed the storage batteries 28 areconnected with the motors, as by a switch 36.

The boat may be steered electrically in the following manner: Disconnectthe propeller shafts 25 from each other conveniently by uncoupling thegears 29 from the shafts. It will be seen that the field 37 of eachmotor (shunt wound) is provided with a. variable resistance, consistingof resistance elements 38 and a traveling contact 39. Thus, by varyingthe ratio of the resistances in the two field shunts, it is possible tocause the propellers to revolve at dif-' ferent relative speeds, andthereby to secure a turning effect on theboa-t. We prefer to accomplishthis result by mounting the'contacts 39 to travel in unison,convenientlyby connecting them as one part withinsu between. Therelative'arrangement resistance elements and traveling is such that themovement of the u tacts 39 in one direction. cuts resistance to onefield and out of the other, while reverse movement of the unitedcontacts reverses-the While the diagrammatic {vi indicates that theunited-contacts 39 trav rectilinearly, it-will be obvious that the twovariable resistances might be merely a dou-, ble rheost-at' with adouble pivoted contact.

The numeral 40 designates a hinged cap at the forward end of the vessel,adapted to be opened from within the vessel by any suitable means, as bya'hand-wheel, shaft and worm 41 and a worm gear are 42. The opening ofthis cap uncovers an aperture filled the mouth 'of the torpedo tube 43.-For righting the vessel after the discharge of the torpedo, alongitudinally movable 125: Wei ht 44 is provided within the vessel, preerably at the bottom thereof; a cable being secured at the two ends tosaid weight and passing around a drum 45, whereby the -nally of thevessel. In addition to this means for righting the vessel as topitching, we may provide ydraulic means such as a pair of tanks 46disposed fore an aft. By filling one and emptying, the other the cen terof gravity is displaced toward the, front or rear of the vessel.

Suitable ventilators project upward through the deck of the vessel. Inorder to prevent water or spray entering these ventilators from beingdashed about the interior of the vessel, we inclose thelowerrportions ofthe ventilators in receptacles or traps 56, having air outlets 57 abovethe ower. extremities of the ventilators. These receptacles are providedthrough or adjacent their bottoms with suitable means for removingcollected water, as'a simple cook 58, or a cock andv pump 59. The'waterso removed may be disposed of in any suitable manner.

Preferably, though not necessarily, the engine 26 is of the kerosene oiltype, as with this form of internal combustion engine considerableeconomy of space is possible.

We wish to call attention to the fact that the chamber formed betweenthe'conning tower and the bucket 10 is air-tight as well as water-tight,whereby the chamber will serve to buoy up the vessel should part or allof the hull become filled with water.

What we claim as new is:

l. A submarine vessel, havin a conning tower projecting upward thererom, and a bucket-shaped bottom secured at the base of the conning towerwithin and wallin air the interior of the tower from the remainder ofthe interior of the vessel,'said bucketshaped bottcan beingv depressibleso as to afford free access to the interior of the c011- ning tower.

2. A submarine vessel having a conning tower projecting upwardtherefrom, and a bucket-shaped bottom removably secured at the base ofthe conning tower within and walling 011' the int ior of the tower fromlgsaid bucket-shaped bottom being provided I with water-tight manholes.

3. A submarine vessel, havin tower projecting upward therefrom, and abucket-shaped bottom removably secured-at the base of the conning towerwithin and having water-tight connection therewith, walling 011' theinterior of the towenfrom'the remainder of the interior of the vessel.
